I had the same problem when using the "lo" interface in the l4linux-ore disk image
I have build for OpenTC.

The reason was that ORe can not guess an IRQ for this interface but L4Linux needs
one. You can overwrite the IRQ and the interface by giving something like
"l4ore.oredev=lo l4ore.irqnum=13" on the L4Linux command line.
